Description

Technical Field

[0001] This disclosure relates to a transparent display device. Background Technology

[0002] With the advancement of the information society, the demand for display devices for displaying images has increased in various forms. Recently, various display devices such as liquid crystal displays (LCDs), plasma display panels (PDPs), organic light-emitting diode (OLED) displays, and quantum dot light-emitting diode (QLED) displays have been widely used.

[0003] Recently, research has been actively conducted on transparent display devices to allow users to view objects or images arranged on the opposite side of the display device behind the transmission display device.

[0004] Transparent display devices can have high light transmittance in the display area through a transmissive region. However, the resolution of a transparent display device may be degraded due to the transmissive region. The problem with transparent display devices is that the higher the resolution, the greater the decrease in transmittance. Furthermore, because the transmissive region in a transparent display device increases the spacing between subpixels, this spacing may be visible, potentially reducing image quality.

[0025] As will be fully understood by those skilled in the art, the features of the various embodiments of this disclosure can be partially or entirely linked or combined with each other, and can interoperate and be technically driven with each other in a variety of ways. The embodiments of this disclosure can be performed independently of each other or together in a mutually dependent manner.

[0026] In the following, examples of transparent display devices according to this disclosure will be described in detail with reference to the accompanying drawings. Where possible, the same reference numerals will be used throughout the drawings to refer to the same or similar parts.

[0027] Figure 1 This is a perspective view of a transparent display device according to one embodiment of the present disclosure, and Figure 2 This is a planar schematic diagram showing a transparent display panel.

[0028] In the following text, the X-axis indicates the line parallel to the gate line, the Y-axis indicates the line parallel to the data line, and the Z-axis indicates the height direction of the transparent display device 100.

[0029] Although the description is based on implementing the transparent display device 100 according to one embodiment of the present disclosure as an organic light-emitting display device, the transparent display device 100 may be implemented as a liquid crystal display device, a plasma display panel (PDP), a quantum dot light-emitting display (QLED) or an electrophoretic display device.

[0030] Reference Figure 1 and Figure 2 According to one embodiment of the present disclosure, a transparent display device 100 includes a transparent display panel 110, a source driver integrated circuit (IC) 210, a flexible film 220, a circuit board 230, and a timing controller 240.

[0031] The transparent display panel 110 includes a first substrate 111 and a second substrate 112 facing each other. The second substrate 112 may be an encapsulation substrate. The first substrate 111 may be a plastic film, a glass substrate, or a silicon wafer substrate formed using semiconductor processes. The second substrate 112 may be a plastic film, a glass substrate, or an encapsulation film. The first substrate 111 and the second substrate 112 may be made of transparent materials.

[0032] The first substrate 111 may include a display area DA with pixels P formed to display images and a non-display area NDA where no images are displayed.

[0033] The display area DA can be configured with a first signal line SL1, a second signal line SL2, and a pixel P, while the non-display area NDA can be configured with a pad area PA for the pads and a strobe driver 205.

[0034] The first signal line SL1 may extend in a first direction (e.g., the X-axis direction) and may intersect with the second signal line SL2 in the display area DA. The second signal line SL2 may extend in a second direction (e.g., the Y-axis direction). Pixel P may be positioned in the area where the first signal line SL1 and the second signal line SL2 intersect and emit predetermined light to display an image.

[0035] The gating driver 205 provides a gating signal to the gating line according to the gating control signal provided from the timing controller 240. The gating driver 205 can be positioned on one side of the display area of ​​the transparent display panel 110, or in the non-display areas of the two peripheral sides of the transparent display panel 110, using a gating driver in-panel (GIP) method. Alternatively, the gating driver 205 can be fabricated in a driver chip, mounted on a flexible film, and attached to one or both peripheral sides of the display area of ​​the transparent display panel 110 using a tape auto-adhesion (TAB) method.

[0036] For example, such as Figure 2 As shown, the gating driver 205 may include a first gating driver 205a disposed in a non-display area NDA disposed above a first peripheral side of the display area DA, and a second gating driver 205b disposed in a non-display area NDA disposed above a second peripheral side of the display area DA, but is not limited thereto.

[0037] If the source driver IC 210 is manufactured in the driver chip, the source driver IC 210 can be mounted on the flexible film 220 by the chip-on-film (COF) method or the chip-on-plastic (COP) method.

[0038] Pads such as power pads and data pads can be provided in the pad area PA of the transparent display panel 110. Lines connecting the pads to the source driver IC 210 and lines connecting the pads to the circuit board 230 can be provided in the flexible film 220. The flexible film 220 can be attached to the pads using an anisotropic conductive film, allowing the pads to be connected to the lines on the flexible film 220.

[0039] Figure 3 It is shown Figure 2 A schematic diagram of one implementation of the pixels set in region A. Figure 4 This is a schematic diagram showing the first signal line, the second signal line, and the pixel. Figure 5 It is a diagram showing the arrangement of subpixels included in the first unit pixel, and Figure 6 This is a diagram showing the arrangement of subpixels included in the second unit pixel.

[0040] Reference Figures 3 to 6 The transparent display panel 110 may include a display area DA with pixels P for displaying images and a non-display area NDA for not displaying images.

[0041] The display area DA includes a transmissive area TA and a non-transmissive area. The transmissive area TA is the region through which most of the external incident light passes, and the non-transmissive area is the region through which most of the external incident light cannot pass. For example, the transmissive area TA can be a region with a transmittance greater than α% (e.g., 90%), and the non-transmissive area can be a region with a transmittance less than β% (e.g., 50%). In this case, α is greater than β. Due to the transmissive area TA, the user can see objects or backgrounds arranged above the rear surface of the transparent display panel 110.

[0042] The non-transmissive region may include a first non-transmissive region NTA1 and a second non-transmissive region NTA2 in which a first signal line SL1 is disposed, a third non-transmissive region NTA3 and a fourth non-transmissive region NTA4 in which a second signal line SL2 is disposed, and a pixel P.

[0043] The first signal line SL1 may extend from the display area DA in a first direction (e.g., the X-axis direction). Multiple first signal lines SL1 may be configured to be spaced apart from each other.

[0044] For example, the first signal line SL1 may include a gate line. In this case, the first signal line SL1 may include, for example... Figure 4The two gate lines are shown. For example, the first signal line SL1 may include a first gate line GL1 and a second gate line GL2. The first gate line GL1 is used to provide a gate signal to a plurality of sub-pixels SP1 and SP3 included in the first unit pixel UP1, and the second gate line GL2 is used to provide a gate signal to a plurality of sub-pixels SP2 and SP3 included in the second unit pixel UP2.

[0045] In the following text, when the first signal line SL1 comprises multiple lines, one first signal line SL1 may refer to a signal line group consisting of multiple lines. For example, when the first signal line SL1 comprises a first gating line GL1 and a second gating line GL2, one first signal line SL1 may refer to a signal line group consisting of the first gating line GL1 and the second gating line GL2.

[0046] The second signal line SL2 may extend from the display area DA in a second direction (e.g., the Y-axis direction) and may intersect the first signal line SL1 in the display area DA. Multiple second signal lines SL2 may be configured to be spaced apart from each other.

[0047] For example, the second signal line SL2 may include a data line. In this case, the second signal line SL2 may include, for example... Figure 4 The two data lines are shown. For example, the second signal line SL2 may include a first data line DL1 and a second data line DL2. The first data line DL1 is used to provide data voltage to a plurality of sub-pixels SP1 and SP3 included in the first unit pixel UP1, and the second data line DL2 is used to provide data voltage to a plurality of sub-pixels SP2 and SP3 included in the second unit pixel UP2.

[0048] although Figure 4 Although not shown in the diagram, the second signal line SL2 may also include at least one of a pixel power line, a common power line, or a reference line.

[0049] In the following text, when the second signal line SL2 comprises multiple lines, one second signal line SL2 may refer to a signal line group consisting of multiple lines. For example, when the second signal line SL2 comprises a first data line DL1, a second data line DL2, a pixel power line, a common power line, and a reference line, one second signal line SL2 may refer to a signal line group consisting of the first data line DL1, the second data line DL2, the pixel power line, the common power line, and the reference line.

[0050] The pixel power line can provide a first power supply to the driving transistor of each of the sub-pixels SP1, SP2, and SP3 disposed in the display area DA. The common power line can provide a second power supply to the cathodes of the sub-pixels SP1, SP2, and SP3 disposed in the display area DA. In this case, the second power supply can be a common power supply provided to the sub-pixels SP1, SP2, and SP3. The reference line can provide an initialization voltage (or sensing voltage) to the driving transistor of each of the sub-pixels SP1, SP2, and SP3 disposed in the display area DA.

[0051] The transmission region TA can be positioned between adjacent first signal lines SL1. Furthermore, the transmission region TA can be positioned between a first non-transmissive region NTA1, which has an odd number of rows of first signal lines SL1-1, and a second non-transmissive region NTA2, which has an even number of rows of first signal lines SL1-2. In other words, the transmission region TA can be positioned between the odd-numbered rows of first signal lines SL1-1 and the even-numbered rows of first signal lines SL1-2.

[0052] The transmission region TA can be positioned between adjacent second signal lines SL2. Specifically, the transmission region TA can be positioned between a third non-transmissive region NTA3, which has an odd number of rows of second signal lines SL2-1, and a fourth non-transmissive region NTA4, which has an even number of rows of second signal lines SL2-2. That is, the transmission region TA can be positioned between the odd number of rows of second signal lines SL2-1 and the even number of rows of second signal lines SL2-2. The transmission region TA can be surrounded by two first signal lines SL1-1 and SL1-2 and two second signal lines SL2-1 and SL2-2.

[0053] The length of the transmission region TA in the first direction can be longer than the length of the transmission region TA in the second direction. The width of the first signal line SL1 extending in the first direction can be smaller or narrower than the width of the second signal line SL2 extending in the second direction. The first signal line SL1 includes gating lines GL1 and GL2, while the second signal line SL2 may include one of a pixel power line and a common power line in addition to data lines DL1 and DL2. Since the pixel power line and the common power line are subjected to high voltage, the width of each of the pixel power line and the common power line should be wider than the width of each of the gating lines GL1 and GL2 or the data lines DL2 and DL2. Therefore, the width of the second signal line SL2 can be wider than the width of the first signal line SL1.

[0054] According to one embodiment of the present disclosure, the transparent display panel 110 can improve its transmittance by increasing the size of a transmissive region TA. When the size of the transmissive region TA is increased, the length of at least one of the first signal line SL1 or the second signal line SL2 surrounding the transmissive region TA can also be increased.

[0055] When the length of the transmission region TA in the second direction is made longer, the length of the second signal line SL2 disposed between two adjacent transmission regions TA can be increased. Conversely, when the length of the transmission region TA in the first direction is made longer, the length of the first signal line SL1 disposed between two adjacent transmission regions TA can be increased. Since the width of the first signal line SL1 is smaller or narrower than the width of the second signal line SL2, the area increase rate due to the increase in length is lower. Since the areas where the first signal line SL1 and the second signal line SL2 are disposed correspond to the non-transmissive areas that do not transmit light, the size increase rate of the non-transmissive areas is less when the length of the transmission region TA in the first direction increases than when the length of the transmission region in the second direction increases.

[0056] Therefore, the transparent display panel 110 according to one embodiment of the present disclosure can increase the size of the transmission region TA and improve the transmittance by increasing the length of the transmission region TA in the first direction.

[0057] Pixel P is positioned in the intersection area IA where the first signal line SL1 and the second signal line SL2 intersect, and displays an image by emitting predetermined light. The light-emitting area EA may correspond to the area in pixel P used for emitting light.

[0058] like Figure 3 As shown, pixel P may include a first pixel P1 that overlaps with a portion of the first signal line SL1-1 in odd-numbered rows and a second pixel P2 that overlaps with a portion of the first signal line SL1-2 in even-numbered rows.

[0059] The first pixel P1 can be located in the intersection region where the first non-transmissive region NTA1, which has an odd number of rows of first signal lines SL1-1, and the third non-transmissive region NTA3, which has an odd number of rows of second signal lines SL2-1, intersect each other. Furthermore, the first pixel P1 can be located in the intersection region where the first non-transmissive region NTA1, which has an odd number of rows of first signal lines SL1-1, intersects each other, and the fourth non-transmissive region NTA4, which has an even number of rows of second signal lines SL2-2, intersects each other. Since the arrangement order of the sub-pixels SP1, SP2, and SP3 of the first pixel P1 that overlaps with a portion of the odd-numbered rows of second signal lines SL2-1 is equal to the arrangement order of the sub-pixels SP1, SP2, and SP3 of the second pixel P2 that overlaps with a portion of the even-numbered rows of second signal lines SL2-2, this description can be based on the first pixel P1 being located in the intersection region where the first signal lines SL1-1 and the second signal lines SL2-1, which have an odd number of rows, intersect each other.

[0060] The second pixel P2 can be located in the intersection area where the second non-transmissive region NTA2, which has even-numbered rows of the first signal lines SL1-2, and the third non-transmissive region NTA3, which has odd-numbered rows of the second signal lines SL2-1, intersect. Furthermore, the second pixel P2 can be located in the intersection area where the second non-transmissive region NTA2, which has even-numbered rows of the first signal lines SL1-2, and the fourth non-transmissive region NTA4, which has even-numbered rows of the second signal lines SL2-2, intersect. Since the arrangement order of the sub-pixels SP1, SP2, and SP3 of the second pixel P2 that overlap with a portion of the odd-numbered rows of the second signal lines SL2-1 is equal to the arrangement order of the sub-pixels SP1, SP2, and SP3 of the second pixel P2 that overlap with a portion of the even-numbered rows of the second signal lines SL2-2, this description can be based on the second pixel P2 being located in the intersection area where the first signal lines SL1-2 and the second signal lines SL2-2, which intersect.

[0061] Each of the first pixel P1 and the second pixel P2 may include a first unit pixel UP1 and a second unit pixel UP2. That is, in a transparent display panel 110 according to one embodiment of the present disclosure, two unit pixels UP1 and UP2 may be provided in the intersection area IA where the first signal line SL1 and the second signal line SL2 intersect each other.

[0062] In a transparent display panel 110 according to one embodiment of the present disclosure, since two unit pixels UP1 and UP2 are provided in an intersecting area, the size of the transmissive area TA can be increased, thereby improving the transmittance and simultaneously obtaining a high resolution.

[0063] Each of the first unit pixel UP1 and the second unit pixel UP2 may include at least two of the first sub-pixel SP1, the second sub-pixel SP2, and the third sub-pixel SP3. In this case, one of the first sub-pixel SP1, the second sub-pixel SP2, and the third sub-pixel SP3 may be set to repeat in the first unit pixel UP1 and the second unit pixel UP2.

[0064] For example, the second sub-pixel SP2 can be set to repeat in the first unit pixel UP1 and the second unit pixel UP2. That is, the first unit pixel UP1 may include the first sub-pixel SP1 and the third sub-pixel SP3, and the second unit pixel UP2 may include the second sub-pixel SP2 and the third sub-pixel SP3.

[0065] The first sub-pixel SP1 may include a first emitting region EA1 that emits light of a first color, the second sub-pixel SP2 may include a second emitting region EA2 that emits light of a second color, and the third sub-pixel SP3 may include a third emitting region EA3 that emits light of a third color.

[0066] As an example, the first to third emitting regions EA1, EA2, and EA3 can emit light of different colors from each other. For example, the first emitting region EA1 can emit green light, the second emitting region EA2 can emit blue light, and the third emitting region EA3 can emit red light. However, the emitting regions are not limited to this example. Furthermore, the arrangement order of sub-pixels SP1, SP2, and SP3 can be changed in various ways.

[0067] In the following description, for ease of description, the description will be based on the premise that the first sub-pixel SP1 is a green sub-pixel for emitting green light, the second sub-pixel SP2 is a blue sub-pixel for emitting blue light, and the third sub-pixel SP3 is a red sub-pixel for emitting red light. Furthermore, although this description is based on the premise that the first unit pixel UP1 includes the first sub-pixel SP1 and the third sub-pixel SP3 and the second unit pixel UP2 includes the second sub-pixel SP2 and the third sub-pixel SP3, this disclosure is not limited to this example.

[0068] In a transparent display panel 110 according to one embodiment of the present disclosure, the arrangement order of the first to third sub-pixels SP1, SP2, and SP3 in the first pixel P1 is different from the arrangement order of the first to third sub-pixels SP1, SP2, and SP3 in the second pixel P2. The first pixel P1 and the second pixel P2 may differ from each other in the position of at least one of the first sub-pixels SP1, the second sub-pixel SP2, or the third sub-pixel SP3.

[0069] Specifically, the first pixel P1 and the second pixel P2 differ from each other in the positions of the first unit pixel UP1 and the second unit pixel UP2. In the first pixel P1, the first unit pixel UP1 may be set in a first direction (e.g., direction D1) based on the intersection region IA, and the second unit pixel UP2 may be set in a second direction (e.g., direction D2) opposite to the first direction (e.g., direction D1). On the other hand, in the second pixel P2, which is different from the first pixel P1, the first unit pixel UP1 may be set in the second direction (e.g., direction D2) based on the intersection region IA, and the second unit pixel UP2 may be set in the first direction (e.g., direction D1).

[0070] Furthermore, the arrangement order of the first sub-pixel SP1 and the third sub-pixel SP3 included in the first unit pixel UP1 within the first pixel P1 and the second pixel P2 can be different from each other. Therefore, the positions and shapes of the first sub-pixel SP1 and the third sub-pixel SP3 included in the first unit pixel UP1 within the first pixel P1 and the second pixel P2 can be different from each other.

[0071] Specifically, each of the first pixel P1 and the second pixel P2 may have four sub-pixel regions based on the intersection region IA, so that the four sub-pixels can be set in four sub-pixel regions. Each of the first pixel P1 and the second pixel P2 may include a first sub-pixel region overlapping a portion of the first signal line SL1, a second sub-pixel region overlapping a portion of the second signal line SL2, a third sub-pixel region overlapping a portion of the first signal line SL1 and facing the first sub-pixel region, and a fourth sub-pixel region overlapping a portion of the second signal line SL2 and facing the second sub-pixel region.

[0072] In the first pixel P1, the first unit pixel UP1 can be positioned in a first direction (e.g., direction D1) based on the intersection region IA. The first sub-pixel SP1 included in the first unit pixel UP1 of the first pixel P1 can be positioned above the first signal line SL1-1 in the odd-numbered rows. The first sub-pixel SP1 included in the first unit pixel UP1 of the first pixel P1 can be positioned in the first sub-pixel region of the first pixel P1. In one embodiment, the first sub-pixel SP1 included in the first unit pixel UP1 of the first pixel P1 can include a protruding region extending along the first signal line SL1-1 in a direction on the first side.

[0073] The third sub-pixel SP3 included in the first unit pixel UP1 of the first pixel P1 can be disposed above the second signal line SL2. The third sub-pixel SP3 included in the first unit pixel UP1 of the first pixel P1 can be disposed in the second sub-pixel region of the first pixel P1. In one embodiment, the third sub-pixel SP3 included in the first unit pixel UP1 of the first pixel P1 can include a protruding region extending along the second signal line SL2 in the direction of the second side.

[0074] In the second pixel P2, unlike the first pixel P1, the first unit pixel UP1 can be positioned in a second direction (e.g., direction D2) based on the intersection region IA. The first sub-pixel SP1 included in the first unit pixel UP1 of the second pixel P2 can be positioned above the first signal lines SL1-2 in even-numbered rows. Unlike the first pixel P1, the first sub-pixel SP1 included in the first unit pixel UP1 of the second pixel P2 can be positioned in the third sub-pixel region of the second pixel P2. In one embodiment, the first sub-pixel SP1 included in the first unit pixel UP1 of the second pixel P2 can include a protruding region protruding along the first signal line SL1-2 in a direction opposite to the direction in which the first sub-pixel SP1 of the first pixel P1 protrudes.

[0075] The third sub-pixel SP3, included in the first unit pixel UP1 of the second pixel P2, can be disposed above the second signal line SL2. Unlike the first pixel P1, the third sub-pixel SP3, included in the first unit pixel UP1 of the second pixel P2, can be disposed in the fourth sub-pixel region of the second pixel P2. In one embodiment, the third sub-pixel SP3, included in the first unit pixel UP1 of the second pixel P2, can include a protruding region extending along the second signal line SL2 in the direction of the second side.

[0076] When the first unit pixel UP1 of the first pixel P1 and the first unit pixel UP1 of the second pixel P2 have the above arrangement order, such as Figure 5 As shown, the diagonal lengths c1 and c2 of the first sub-pixel SP1 of the first pixel P1 and the first sub-pixel SP1 of the second pixel P2 can be longer than the vertical length "b" of the first sub-pixel SP1 of the first pixel P1 and the first sub-pixel SP1 of the second pixel P2. Furthermore, the diagonal lengths c1 and c2 of the first sub-pixel SP1 of the first pixel P1 and the first sub-pixel SP1 of the second pixel P2 can be shorter than the horizontal length "a" of the first sub-pixel SP1 of the first pixel P1 and the first sub-pixel SP1 of the first pixel P2.

[0077] When the first sub-pixel SP1 is a green sub-pixel, the brightness of the green light can be greater than the brightness of each of the red and blue lights. According to one embodiment of this disclosure, the transparent display panel 110 can achieve optimal image quality by uniformly setting high-brightness green sub-pixels.

[0078] The first pixel P1 and the second pixel P2 can be identical in position to each other as to the first unit pixel UP1 and the second unit pixel UP2, and can also be identical in the arrangement order of the first sub-pixel SP1 and the third sub-pixel SP3 included in the first unit pixel UP1. Since the first sub-pixel SP1 is positioned at the same location in each of the first pixel P1 and the second pixel P2, the first sub-pixel SP1 can be positioned on a line parallel to the second signal line SL2 or the first signal line SL1. In this case, the green sub-pixel can be identified as a line in the image. When the green sub-pixel has high brightness, the line composed of green sub-pixels can be easily identified.

[0079] In a transparent display panel 110 according to one embodiment of the present disclosure, the first sub-pixel SP1 can be disposed at different positions in the first pixel P1 and the second pixel P2. In the first pixel P1, the first sub-pixel SP1 can be disposed in the first sub-pixel region, and in the second pixel P2, the first sub-pixel SP1 can be disposed in the third sub-pixel region (disposed of facing the first sub-pixel region) instead of the first sub-pixel region. Therefore, in the transparent display panel 110 according to one embodiment of the present disclosure, since the first sub-pixel SP1 is not disposed as a line parallel to the second signal line SL2, the first sub-pixel SP1 may not be recognizable as a line in the image.

[0080] Furthermore, the first sub-pixel SP1 of the first pixel P1 may include a protruding area protruding along the first signal line SL1-1 in the direction of the first side, and the first sub-pixel SP1 of the second pixel P2 may include a protruding area protruding along the first signal line SL1-2 in the direction of the third side opposite to the direction of the first sub-pixel SP1 of the first pixel P1.

[0081] In a transparent display panel 110 according to one embodiment of the present disclosure, each of the first sub-pixels SP1 of the first pixel P1 and the first sub-pixels SP1 of the second pixel P2 protrudes along the first signal line SL1, thereby increasing the light-emitting area of ​​the first sub-pixel SP1 and reducing the size of the non-light-emitting area NEA. Therefore, the transparent display panel 110 according to one embodiment of the present disclosure can improve luminous efficiency.

[0082] Furthermore, in a transparent display panel 110 according to one embodiment of the present disclosure, the protruding regions respectively provided in the first sub-pixel SP1 of the first pixel P1 and the first sub-pixel SP1 of the second pixel P2 are provided in different directions, thereby allowing the first sub-pixel SP1 to be provided more evenly.

[0083] The first pixel P1 and the second pixel P2 can differ in the arrangement order of the second sub-pixel SP2 and the third sub-pixel SP3 included in the second unit pixel UP2 and the first unit pixel UP1. Therefore, the positions and shapes of the second sub-pixel SP2 and the third sub-pixel SP3 included in the second unit pixel UP2 can differ from each other in the first pixel P1 and the second pixel P2.

[0084] Specifically, in the first pixel P1, the second unit pixel UP2 can be positioned in a second direction (e.g., direction D2) based on the intersection region IA. The second sub-pixel SP2 included in the second unit pixel UP2 of the first pixel P1 can be positioned above the first signal line SL1-1 in the odd-numbered rows. The second sub-pixel SP2 included in the second unit pixel UP2 of the first pixel P1 can be positioned in the third sub-pixel region of the first pixel P1. In one embodiment, the second sub-pixel SP2 included in the second unit pixel UP2 of the first pixel P1 can include a protruding region protruding along the first signal line SL1-1 in a direction opposite to the direction in which the first sub-pixel SP1 of the first unit pixel UP1 protrudes.

[0085] The third sub-pixel SP3, included in the second unit pixel UP2 of the first pixel P1, can be disposed above the second signal line SL2. The third sub-pixel SP3, included in the second unit pixel UP2 of the first pixel P1, can also be disposed in the fourth sub-pixel region of the first pixel P1. In one embodiment, the third sub-pixel SP3, included in the second unit pixel UP2 of the first pixel P1, may include a protruding region extending along the second signal line SL2 in a direction opposite to the direction in which the third sub-pixel SP3 of the first unit pixel UP1 protrudes.

[0086] In the second pixel P2, unlike the first pixel P1, the second unit pixel UP2 may be positioned in the first direction (e.g., direction D1) based on the intersection region IA. Unlike the first pixel P1, the second sub-pixel SP2 included in the second unit pixel UP2 of the second pixel P2 may be positioned above the second signal line SL2 instead of above the first signal line. Unlike the first pixel P1, the second sub-pixel SP2 included in the second unit pixel UP2 of the second pixel P2 may be positioned in the second sub-pixel region of the second pixel P2. In one embodiment, the second sub-pixel SP21 included in the second unit pixel UP2 of the second pixel P2 may include a protruding region extending along the second signal line SL2 in a direction on the second side.

[0087] Unlike the first pixel P1, the third sub-pixel SP3 included in the second unit pixel UP2 of the second pixel P2 can be positioned above the first signal lines SL1-2 in even-numbered rows instead of above the second signal line SL2. Unlike the first pixel P1, the third sub-pixel SP3 included in the second unit pixel UP2 of the second pixel P2 can be positioned within the first sub-pixel region of the second pixel P2. In one embodiment, the third sub-pixel SP3 included in the second unit pixel UP2 of the second pixel P2 can include a protruding region extending along the first signal lines SL1-2 in even-numbered rows in a direction on a first side. The third sub-pixel SP3 included in the second unit pixel UP2 of the second pixel P2 can be positioned parallel to the first sub-pixel SP1 of the first unit pixel UP1 of the first pixel P1.

[0088] When the second unit pixels UP2 of the first pixel P1 and the second unit pixels UP2 of the second pixel P2 are arranged in the order described above, the horizontal length a1 between two adjacent second sub-pixels SP2 of the first pixel P1 can be different from the horizontal length a2 between two adjacent second sub-pixels SP2 of the second pixel P2. Specifically, the horizontal length a1 between adjacent second sub-pixels SP2 of the first pixel P1 can be longer than the horizontal length a2 between two adjacent second sub-pixels SP2 of the second pixel P2.

[0089] Each of the first pixel P1 and the second pixel P2 may include two third sub-pixels SP3. In the first pixel P1, the two third sub-pixels SP3 may be positioned facing each other along the second signal line SL2. In the second pixel P2, one of the two third sub-pixels SP3 may be positioned above the first signal line SL1, and the other may be positioned above the second signal line SL2. In a transparent display panel 110 according to one embodiment of the present disclosure, the third sub-pixels SP3 are positioned differently in the first pixel P1 and the second pixel P2, thereby preventing the third sub-pixels SP3 from being identified as a line in the image.

[0090] In both the first pixel P1 and the second pixel P2, two third sub-pixels SP3 can be positioned facing each other along the second signal line SL2. In this case, since the third sub-pixels SP3 are positioned as a line along the second signal line, they can be identified as a line in the image. Because the spacing between the second signal lines SL2 is greater than the spacing between the first signal lines SL1, the line composed of the third sub-pixels SP3 can be more easily identified.

[0091] In a transparent display panel 110 according to one embodiment of the present disclosure, the third sub-pixel SP3 can be arranged differently in the first pixel P1 and the second pixel P2, thereby preventing the third sub-pixel SP3 from being set as a line along the second signal line SL2. Therefore, the transparent display panel 110 according to one embodiment of the present disclosure can prevent the third sub-pixel SP3 from being identified as a line in the image.

[0092] In a transparent display panel 110 according to one embodiment of the present disclosure, sub-pixels SP1, SP2, and SP3 disposed in each of the first pixel P1 disposed above the first signal line SL1-1 in odd-numbered rows and the second pixel P2 disposed above the first signal line SL1-2 in even-numbered rows can be disposed differently as described above. The transparent display panel 110 with the first pixel P1 and the second pixel P2 disposed as described above can have high transmittance, high resolution, and also provide optimal image quality.

[0093] Furthermore, in a transparent display panel 110 according to one embodiment of the present disclosure, a pixel P includes a plurality of edges facing the transmissive region, and each of the plurality of edges of the pixel P has an inclination relative to each of the first signal line SL1 and the second signal line SL2.

[0094] Specifically, pixel P may include a first side S1 and a second side S2 facing the transmission region TA, a third side S3 facing the first side S1, and a fourth side S4 facing the second side S2. For example, pixel P may have a protruding area along the first signal line SL1 in a rhombus shape formed by the four sides S1, S2, S3, and S4. In this case, depending on the size and arrangement of pixel P, the transmission region TA may have a hexagonal or octagonal shape.

[0095] Each of the first side S1, second side S2, third side S3, and fourth side S4 of pixel P can be tilted and not parallel or perpendicular to the first signal line SL1. That is, each of the first side S1, second side S2, third side S3, and fourth side S4 of pixel P can have a tilt angle of 0° to 90° relative to the first signal line SL1. For example, each of the first side S1, second side S2, third side S3, and fourth side S4 of pixel P can be formed by a diagonal line with a tilt angle of 30° to 60° relative to the first signal line SL1.

[0096] Furthermore, each of the first side S1, second side S2, third side S3, and fourth side S4 of pixel P can be tilted without being parallel or perpendicular to the second signal line SL2. That is, each of the first side S1, second side S2, third side S3, and fourth side S4 of pixel P can have a tilt angle of 0° to 90° relative to the second signal line SL2. For example, each of the first side S1, second side S2, third side S3, and fourth side S4 of pixel P can be formed by a diagonal line with an angle of 30° to 60° relative to the second signal line SL2.

[0097] Furthermore, non-transmissive areas can be classified into luminescent areas EA, which are equipped with pixels P to emit light, and non-luminescent areas NEA, which do not emit light.

[0098] The light-emitting area EA can be provided with multiple sub-pixels SP1, SP2 and SP3 to emit light of a predetermined color, and can include a first light-emitting area EA1, a second light-emitting area EA2 and a third light-emitting area EA3 respectively provided in the multiple sub-pixels SP1, SP2 and SP3.

[0099] The non-luminous area NEA can be equipped with a black matrix BM. The black matrix BM can include a first black matrix BM1, a second black matrix BM2, a third black matrix BM3, and a fourth black matrix BM4.

[0100] The first black matrix BM1 can be set in multiple sub-pixels SP1, SP2 and SP3 to prevent color mixing in the multiple sub-pixels SP1, SP2 and SP3.

[0101] The second black matrix BM2 can be set between each of the multiple sub-pixels SP1, SP2 and SP3 and the transmission area TA to prevent light emitted from each of the multiple sub-pixels SP1, SP2 and SP3 from being perceived as a different color of light depending on the viewing angle.

[0102] The third black matrix BM3 can be set between pixels P that are adjacent to each other along the first direction, thereby preventing color mixing between pixels P that are adjacent to each other in the first direction and preventing external incident light from being reflected by the first signal line SL1.

[0103] The fourth black matrix BM4 can be set between pixels P that are adjacent to each other along the second direction, thereby preventing color mixing between pixels P that are adjacent to each other in the second direction and preventing external incident light from being reflected in the second signal line SL2.

[0104] Because the black matrix BM is made of a material that shields or absorbs light, light emitted from sub-pixels SP1, SP2, and SP3 cannot pass through the area where the black matrix BM is located, and external incident light may not be able to pass through the area where the black matrix BM is located. Therefore, the area where the black matrix BM is located corresponds to the non-emitting area NEA that does not emit light.

[0105] Because the black matrix BM shields or absorbs light, it significantly affects the transmittance of the transparent display panel 110. Specifically, when the area where the black matrix BM is located (i.e., the non-light-emitting area NEA) increases, the transmittance of the transparent display panel 110 decreases. On the other hand, when the non-light-emitting area NEA decreases, the transmittance of the transparent display panel 110 can increase.

[0106] A transparent display panel 110 according to one embodiment of the present disclosure has a pixel P structure for reducing the area where the black matrix BM is disposed (i.e., the non-emitting area NEA). In the transparent display panel 110 according to one embodiment of the present disclosure, the pixel P is disposed in the intersection area IA where the first signal line SL1 and the second signal line SL2 intersect each other, and multiple edges S1, S2, S3, and S4 of the pixel P are inclined relative to each of the first signal line SL1 and the second signal line SL2. In the transparent display panel 110 according to one embodiment of the present disclosure, the pixel P is disposed in the intersection area IA where the first signal line SL1 and the second signal line SL2 intersect, and multiple edges S1, S2, S3, and S4 of the pixel P are inclined relative to each of the first signal line SL1 and the second signal line SL2. In the transparent display panel 110 having the above-described pixel P, compared to a transparent display panel having a pixel P that is parallel or perpendicular to the first signal line SL1 and the second signal line SL2, the multiple edges S1, S2, S3, and S4 can reduce the outer length of the transmissive area TA.

[0107] In other words, the transparent display panel 110 according to one embodiment of the present disclosure can reduce the overall size of the second black matrix BM2 disposed between each of the sub-pixels SP1, SP2, and SP3 and the transmissive region TA, the third black matrix BM3 disposed between pixels P arranged adjacent to each other in the first direction, and the fourth black matrix BM4 disposed between pixels P arranged adjacent to each other in the second direction. Therefore, the transparent display panel 110 according to one embodiment of the present disclosure can increase the transmittance by reducing the area where the black matrix BM is disposed (i.e., the non-light-emitting region NEA).

[0108] Furthermore, in a transparent display panel 110 according to one embodiment of the present disclosure, a pixel P is disposed in an intersection region IA where the first signal line SL1 and the second signal line SL2 intersect each other, and the pixel P includes a plurality of sub-pixels SP1, SP2, and SP3 disposed based on the intersection region IA. In the transparent display panel 110 according to one embodiment of the present disclosure, the plurality of sub-pixels SP1, SP2, and SP3 are disposed together based on the intersection region IA, thereby improving the clarity and readability of the image quality.

[0109] Furthermore, in a transparent display panel 110 according to one embodiment of the present disclosure, the first non-emitting region NEA1 disposed among the plurality of sub-pixels SP1, SP2, and SP3 can be tilted relative to each of the first signal line SL1 and the second signal line SL2. For example, a black matrix BM can be disposed at the midpoint of each of the edges S1, S2, S3, and S4 from the intersection region IA to pixel P. In this way, compared to a transparent display panel with a black matrix BM disposed along the first signal line SL1 or the second signal line SL2 among the plurality of sub-pixels SP1, SP2, and SP3, the transparent display panel 110 with the black matrix BM can reduce the size of the first non-emitting region NEA1.

[0110] In other words, the transparent display panel 110 according to one embodiment of the present disclosure can reduce the size of the first black matrix BM1 disposed in the sub-pixels SP1, SP2 and SP3. Therefore, the transparent display panel 110 according to one embodiment of the present disclosure can increase the transmittance as the area providing the black matrix BM (i.e., the non-light-emitting area NEA) is reduced.

[0111] Figure 7A A diagram showing the pixel structure in each of Embodiment 1 and Embodiment 2.

[0112] Reference Figure 7AIn Implementation 1 (Case 1), the arrangement order of sub-pixels is different in the pixels arranged in the odd-numbered rows of the first signal line SL1-1 and in the pixels arranged in the even-numbered rows of the first signal line SL1-2.

[0113] In this case, the pixel set in the first signal line SL1-1 of the odd-numbered row can be configured such that one of the two red sub-pixels can face the blue sub-pixel above the first signal line SL1-1 of the odd-numbered row, while the other of the two red sub-pixels can face the green sub-pixel above the second signal line SL2.

[0114] The pixels set in the first signal line SL1-2 of the even-numbered row can be configured such that one of the two red sub-pixels can face the green sub-pixel above the first signal line SL1-2 of the even-numbered row, and the other of the two red sub-pixels can face the blue sub-pixel above the second signal line SL2.

[0115] Embodiment 2 (Case 2) illustrates an example of a pixel structure disposed above a transparent display panel 110 according to one embodiment of the present disclosure. In Embodiment 2 (Case 2), the arrangement order of the sub-pixels is different in the pixels disposed on the first signal lines SL1-1 in odd-numbered rows and the pixels disposed on the first signal lines SL1-2 in even-numbered rows.

[0116] In this case, the pixels set in the first signal line SL1-1 of the odd-numbered rows can be configured such that two red sub-pixels can face each other above the second signal line SL2, and green and blue sub-pixels can face each other above the first signal line SL1-1 of the odd-numbered rows.

[0117] The pixels set in the first signal line SL1-2 of the even-numbered row can be configured such that one of the two red sub-pixels can face the green sub-pixel above the first signal line SL1-2 of the even-numbered row, while the other of the two red sub-pixels can face the blue sub-pixel above the second signal line SL2.

[0118] Figure 7B The viewing angle in each of Embodiment 1 and Embodiment 2 is shown.

[0119] Reference Figure 7B The horizontal viewpoint represents the viewpoint of sub-pixels of the same color that are adjacent to each other in the horizontal direction; the vertical viewpoint represents the viewpoint of sub-pixels of the same color that are adjacent to each other in the vertical direction; and the diagonal viewpoint represents the viewpoint of sub-pixels of the same color that are adjacent to each other in the diagonal direction. The viewpoint should be 1.5 arcmin or less, and a smaller viewpoint is better. When the viewpoint increases, the spacing between sub-pixels may become more apparent, potentially degrading image quality.

[0120] In Embodiment 1, it can be noted that the horizontal viewing angle between red sub-pixels is 0.88 arcmin, the vertical viewing angle is 0.39 arcmin, and the diagonal viewing angle is 0.93 arcmin. In Embodiment 1, it can be noted that the horizontal viewing angle between green sub-pixels is 1.10 arcmin, the vertical viewing angle is 0.84 arcmin, and the diagonal viewing angle is 1.39 arcmin. Furthermore, in Embodiment 1, it can be noted that the horizontal viewing angle between blue sub-pixels is 1.10 arcmin, the vertical viewing angle is 0.83 arcmin, and the diagonal viewing angle is 1.12 arcmin.

[0121] In the transparent display panel 110 having the pixel structure of Embodiment 1, the maximum diagonal viewing angle between green sub-pixels is 1.39 arcmin. This value exceeds 1 arcmin but is less than or equal to 1.5 arcmin, and has a low level of recognition for green sub-pixels. Therefore, the transparent display panel 110 having the pixel structure of Embodiment 1 can provide good image quality without any reduction in image quality.

[0122] In Embodiment 2, it can be noted that the horizontal viewing angle between red sub-pixels is 0.88 arcmin, the vertical viewing angle is 0.39 arcmin, and the diagonal viewing angle is 1.07 arcmin. In Embodiment 2, it can be noted that the horizontal viewing angle between green sub-pixels is 1.10 arcmin, the vertical viewing angle is 0.59 arcmin, and the diagonal viewing angle is 0.93 arcmin. Furthermore, in Embodiment 2, it can be noted that the horizontal viewing angle between blue sub-pixels is 1.10 arcmin, the vertical viewing angle is 0.83 arcmin, and the diagonal viewing angle is 1.11 arcmin.

[0123] In the transparent display panel 110 having the pixel structure of Embodiment 2, the maximum diagonal viewing angle between blue sub-pixels is 1.11 arcmin. This value corresponds to a value that is greater than 1 arcmin but significantly less than 1.5 arcmin. Therefore, in the transparent display panel 110 having the pixel structure of Embodiment 2, the level of blue sub-pixel recognition is very low.

[0124] Therefore, the transparent display panel 110 with the pixel structure of Embodiment 2 can provide good image quality.

[0125] According to this disclosure, two unit pixels can correspond to one transmissive region. Therefore, the overall size of the transmissive region is increased, thereby enabling the transparent display device of the present invention to have both high transmittance and high resolution.

[0126] Furthermore, according to this disclosure, the arrangement order of subpixels can be different in the second pixel overlapping a portion of the odd-numbered row of the first signal lines and the second pixel overlapping a portion of the even-numbered row of the second signal lines. The transparent display device of this disclosure can have an optimal pixel structure to prevent image quality degradation.

[0127] Furthermore, according to this disclosure, multiple sub-pixels are set together based on the intersection area where the first signal line and the second signal line intersect each other, thereby improving the clarity and readability of the image quality.

[0128] Furthermore, according to this disclosure, each of the multiple edges of a pixel can be set to have a tilt, and the outer length of the transmissive region can be minimized. Therefore, according to this disclosure, the area where the black matrix is ​​set (i.e., the non-emitting region) can be reduced, and the transmittance can be improved.

[0129] It will be apparent to those skilled in the art that the present disclosure described above is not limited to the above embodiments and drawings, and that various substitutions, modifications, and variations can be made to the present disclosure without departing from the spirit or scope thereof. Therefore, the scope of protection of this disclosure is defined by the appended claims, and it is intended that all variations or modifications derived from the meaning, scope, and equivalent concepts of the claims fall within the scope of protection of this disclosure.
